SOUND-REPRODUOER.

Specification of Letters Patent.

Patented May 15, 1906.

Original application filed Mey18, 1904, Serial No. 208,539- Divifled amtthis application filed April25, 1905. Serial No. 267,305.

, To all whom it may concern:

Be it known that I, RoBER'r HEAD, a citizen of the United States, residing at New York, borough of Manhattan, in the county of New YorkandState of New .York, have invented certainnew and useful Improvements in Sound-Reproducers, of which the following is a specification.

My invention is a reproducer for honographs and talking-machines general y, and it is a division of a prior application for Letters Patent of the United States filed by me on May 18, 1904, Serial No. 208,539.

The object of the invention is the provision of a reproducer which may be used interchangeably in connection either with a graphophone-record or a gramophone-rec-' Broadly stated, my invention consists of a sound-reproducer provided with a plurality of styluses, one of which is adapted for use on a graphophone-record and another is adapted to be used in connection with a gramophone-record; In other words, the styluses of my reproducer may be used on records having curvilinear surfaces and plane surfaces regardless of the movement which may be given to the record-that is to say, the

,difierent styluses are capable of use on records which are distinguished by vertical and lateral undulations.

Reference is to be had to the accompanying drawings, forming a part of this specification, wherein like characters of reference indicate corresponding partsin all the figures.

Figure 1 is a side elevation of a soundreproducer embodying my invention and apted for use in-,.connection with a (graphophone-record or a gramophone-recor a part of the reproducer being broken away. Fig. 2

is a view in rear elevation of the re roducer shown by Fig. 1, illustrating one o the styluses in cooperative relation to a amophonerecord. Fig. 3 is'another view 111 side elevation, showing the reproducer adjusted to bring the other stylus into cooperative engaiement with a graphophone-record.

designates a reproducer, which is shown by the drawings. as a horn having. a vibratory member or diaphragm "which is adapted to be actuated by either of a plurality of styluses. As shown, the reproducer ,A, has a sound-box B ,which is conical in shape and is closed at its apex, This conical sound-box may be made of an suitable or appropriate material, and it is a apted to have vibratlons imparted thereto by the cooperation of a styius with a sound-record.

O D designate a plurality of styluses adapted for cooperation with curvilinear and plane records, res ectively. These styluses may" be connecte in any way with the diaphragm or sound-box of the sound-reproducer; but, as shown, I employ an arm or member E as the means for operatively connecting the tWo styluses to the reproducer. The arm has a ivotal connection at 6 with a bracket F, the

atter being attached fixedly to the'reproducer A, whereby the arm is adapted to have movement with relation to said reproducer.

The arm is attached or connected in any appropriate way at a point intermediate of its ength to the diaphragm B, and said arm is shown as extendin beyond a side of the reroducer in order that it may (present the styus D to a gramophons-reeor (indicated at G in the drawin s.) The styluses appropriate materialas, for instance, metal, g ass, or any other (preferred substance. The stylus O is attache to or mounted on the arm D may be of any suitable or E in a suitable wayas, for example, by cementin riveting, or otherwise fastening said stylus irectl to the arm at a point intermediateof its ength. The other stylus D is shown in the form of a pin, which is mounted in a stylus-holder d, the latter beinlg'lprovided at the free end of the arm E. e stylusholder may be of any suitable or appro riate constructionwhich will enable, the sty us D to be secured firmly and detachably in or to the arm E. The stylus 0 extends from the arm E in a difierent direction from the stylus D, and in one embodiment of the invention the two styluses are connected to the arm so as to lie at rightangles one to the other, although this special organization of styluses is not materia The reproducer A may be adjusted in position to present either of the styluses to the sound-record. As shown by Flgs 1 and 2, the reproducer occupies a positlon wherein the arm E is substantially vertical, and the stylus Dis 'ada ted to cooperate witha gramophone-record The reproducer may, how' ever, beadjusted bodily to move the arm E to a substantially horizontal position, as in dated by Fig. 3. thereby bringing the stylus G into vcooperativerelation to a curvilinear reproducer, into cooperative relation to one record H, such as a graphophone-record.

It will be understood that my invention is not restricted to the particular type of reproducer herein disclosed'and that the gist of the invention consists of a reprodueer havinga plurality of Styluses which are adapted for use in connection with a record having verti.

cal undulations or a record having lateral undulations, such as graphophone .and grainephone records, respectively.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A phonograph reproducer provided with a plurality of styluses arranged and adapted for use respectively in connection with graphophone and gramophone records.

2. A phonograph reproducer provided with two styluses, one being arranged for use in connection with a gra hophone-record, and the other with a grainophone-record.

3. A phonograph-reproducer having a stylus adapted for use on a graphophone-record, and also provided with a stylus arranged to operate on a grainophone-record; said sty luses being in different planes and adapted to be brought, by a change in the position of the of the specified types of records.

I 4. A phonograph reproducer provided 1 with two Styluses; said reproducer being rotatable whereby one stylus may be brought into coi'iperative relation to a graphophonerecord, and the other into like relation toa gramophone-record.

5. A phonograph reproducer having a member provided with a stylus adapted to cooperate with a graphophone-record, and provided also with a stylus ada )ted to cooperate with a grarnophone-record 6. A phonograph reproducer provided with a plurality of reproducingstyluses, one or more of the stylus-points being in a different plane from the others, said reproducer being capable of being positioned to place either of said styluses into cooperative relation. to a record.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ROBERT HEAD.
